Hello,
When I first installed our Adtran Netvanta 3120 router, I put the firmware under the R11.5.1 under the Current Feature Release on our router. I noticed that there is also the Current Extended Maintenance Release R11.4.2 also.
Which version should be used as the primary firmware on the router? Currently I have 11.5.0 but see that 11.5.1 is available.
Thanks
